When buying a PSU, you need to take into account how much energy your computer's actually going to need:
- The Graphics Card is going to be your biggest drain (if you have a separate graphics card)

Essentially, each component will have a requirement, and that should be stated on the packaging/website e.t.c. Check that, and make sure that whatever that adds up to, your PSU gives that and then a little bit more (you don't want the PSU being pushed to its limit)
